“…However, there is a risk that the electromagnetic (EM) propagation of the WPT could cause some level of interference on surrounding equipment and Internet of Things (IoT) and other wireless networks [10]. It is expedient to note that there is unrestricted placement of WPT units around the city and at times in car parks located at hospitals, industrial areas, railway stations etc, where interferences could occur.…”

With the apparent reliability of wireless power transfer technology, Original Equipment Manufacturers are gradually migrating electric vehicle production charging modes from conductive to wireless. The increased users of electric vehicle wireless power transfer will introduce additional electromagnetic signals in the low frequency bandwidth which could cause interferences to various wireless operating systems. It is worth noting, vice versa, that the operation of the wireless power transfer can also be affected by near field propagated electromagnetic signals. This study shows a simplistic method to secure the electric vehicle's wireless power transfer operation from interference by providing simple resonant frequency hopping. A wireless power transfer system with a consolidated 85kHz, recommended by the Society of Automotive Engineers and non-standardized operating frequency of 250kHz was designed to this effect. The selection of 250kHz was based on a separate study detailed in this report.
